Question by Jde · Jul 18, 2012 at 02:23 PM · lightlightmapbakebeastambient

How do I prevent the Ambient Light from influencing lightmap bakes?

I'm using a skylight to provide the ambient contribution when I bake lightmaps, but the 'Ambient Light' present in every scene (in Edit > Render Settings) also always contributes.

I need the 'Ambient Light' at runtime to light dynamic objects. Which means every time I bake I have to set it to black, then remember the settings and reset it to the correct ambient colour for runtime.

Is there a way to just set the 'Ambient Light' so that it doesn't contribute to the lightmap bake?

I suggest you write an editor script that:

  • Remembers the ambient light

  • Initiates a Bake() from code

  • Restores the ambient light

Sorry, too late to contemplate writing this, but here's a starting point:

Yeah that might be my only option. I was hoping it was just an option I missed but I guess not.
